legs Carrying@ their upper endsy an: 'annu- Y' i lar or ring-part-2 of' channel formation, the bot-tomof the channel Vbeing open and :communlcating with ahop-per8. The two parts of .the channel or ring-member 2 are united at intervals by cross Webs 4. Extending inwardly from the member2 are supporting arms l5 carrying at their inner ends` a platform 6 having a centrally disposedbearing member 7. lA vertically ,disposed shafting 8 is keyed vin the bearing 7 and is properly lstepped-or shouldered so as to rest on the upper face of the platform 6, as clearly shown 1n the drawin`gs.l This shatis car? ried upwardly and has reduced portions 9 and 10' for a purpose Vto be llater described.

A horizontal sleeve Y 11 is ysupported "in the frame' and carries a shaft v12 having on its Outer end a driving gear'lB connected toV any suitable source of power. Abeveledpinion 14 is secured' tof the inner end ofthe shaft -12 l for a purposeto be. later described.

will be understoodthat thefbearingslfor the` 27 iS WSllPPItedo-n the iange 22 Y' lris provided .with an upwardlyextending v 4' eo I' vgear 32 which meshes with beveled pinions 33 secured to the inner ends of the rolls 28. The rolls 28 and 29 each carry a gear wheel 34, which mesh, so that as the gear 32 ro- .tates it imparts rotary movement to the rolls 29vwhich, in turn, impart rotary movement to the rolls 28. r'he annular ring35 is secured to the upper iiiace of the gear 32, by bolts 36, or suitable fastening means, and this ring is used for holding the beveled gears 33 on the ends oit the rolls 29.

An upwardly extending sleeve 37 is 'formed on the upper face of the gear 32 and is stepped to form the reduced portions 38 and 39. A gear wheel 40 is supported on the shoulder of the sleeve 37, formed by the reduced portion 387 and is secured in position by means of screws 41.

A casting 42 is rotatably mounted on the shoulder i of the sleeve 37, formed by the reduced portion 39, and this casting is provided with discharge spouts 43 adapted to communicate with discharge openinos 44 formed in the casting 27 and directed to disn charge onto the separating rolls 28 and 29. An upstanding sleeve 45 is secured to the casting 43 by screws or other' suitable fastening means 46 so as to form a' rigid part of the casting. This sleeve 45 is formed on the lower end with a horizontal flange 47 extending overv the upper ends of the discharge spouts 43. v K Y vA vgear wheel 48 is keyed to the reduced portion 10 of the shaft 8, and meshes with a gear wheel 49 keyed to the upper end oi Va vertical shaft 50 which extends through and is rotatably mounted in the casting 43. A, gearwheel 51 is keyed to the lower end of the shaft `50 and meshes with vthey gear wheel 40. VA gear retainer 52 isreceived on the reduoedportion 10 oi the shaft 8,

and comprises a sleeve 53 having a `flange 54 formed on theA lower endthereof.- rlhe iiange 54 overlies the `gear 48 and extends over the gear 59. ln this way the gears 48 and 49 are held onA their respective shafts and can be easily removed when desired. The sleeve 53 of the gea-r retainer and the reduced portion 10 ot the vshaft each have a semicircular recess cut therein to receive a` semicircular pin 55 having a handle 56 formed on one end.y When vthe handle 56 is turned down the semicircular pin 55 extends across into each of the semicircular recesses and securely holds the retainer on the shaft. lWhen it 1s desired to remove the gears, the

` rhandle 56 is swung up, thereby rotating the pin' so that it sfonly in therecess of the sleeve. of the retainer. When in this position the retainer and gears may be removed.

A ball race 57 is supported on the top of the sleeve 45 and a hopper 58, is hung` from the ball race. This hopper comprises a bowl portion 59 and `an upwardly extending sleeve 60 having an inwardlyv extending ange 61. The flange 61 extends over the ball race as shown. A plurality of discharge openings 62 lead from the bowl 59 and, discharge into. the spouts 43.` A'plate 63 is rotatably mounted in the'bowl of the hopper and has a plurality of openings 64 therein adapted to Vbe brought into registration with the discharge openings 62. y A vertical rod 65 is secured to the plate and the upper endA is curved to form a handle 66.. The rod 65 extends through anl elongated opening formed in a guide plate 67 secured to the bowl by means off screws 68 or other suitable fastening members. A stay rod 69 is provided for bracing the hopper. An inner hopper 70 is provided within the hopper 3 and is spaced therefrom. Each of the hoppers 3 and 70 will be provided with a discharge spout at the bottom. i

Having fully described the detailed construction it is thought 'that the operation of the machine will be clearly understood. As the title of the invention implies, my machineV is adapted and intended for picking beans and for separating imperfect seeds and foreign matter from perfect seeds. The seeds are initially placed into the bowl'59," of the hopper 58, and are fed through the openings 64, in the plate 63 and through the discharge openings 62 to the discharge spouts 43 from which they are discharged onto the rolls 28 and 29. The shaft 12 is rotated through means of the gear`13 and as the beveled pinion 14 meshes with the beveled gear 16 the roll bed is rotated. lThe shaft 8 is stationary andas the roll bed rotates it in turn rotates the castings 27 and 42, with discharge spouts 43 and sleeve 45. The castino4 27 carries the rolls'28r-and 29 with it andV the casting 42 carries the shaft. 50, with its associatedgear wheels 49 and 51, around the stationary shaft 8.y The gear wheel 48, on the lupper endof the shaft 8, beingr stationary, rotary movement will be imparted to the gear wheel 49,'-shaft50 and` gear wheel 51. Gear wheel 51 meshing with gearY wheel 4Q rotates the beveled gear 32 which, meshing with the beveled gears33 of the rolls 29, will vrotate the rolls@ The speed of the rolls may be varied by varying the size ofl the gear wheels 48, 49,y 51, and 40, and the gears 48 .and 49 may berremoved and changed at will by removing the 'means for rotating the bed, means for rotatdischarged into the hopper y3.
